Description

Bread baking device

The present invention relates to a kind of bread baking device, more particularly, relate to a kind of like this bread baking device, it can make the CD-ROM drive motor of kneading raw material and curing the roaster of bread directly cool off.

In general, such bread baking device all is equipped with major diameter belt pulley on the driving shaft that is rotatably mounted in the plate of kneading that bakes case bottom, is connected to this plate of kneading, is connected to small-sized driving wheel and on the driving shaft that is installed on CD-ROM drive motor on the hood and hangs over synchronous belt between this major diameter belt pulley and the small-sized driving wheel.

The rotation of above-mentioned CD-ROM drive motor passes to the plate of kneading through this synchronous belt rotation of reduction of speed, this bread baking device then whereby driving force knead and drop into the raw material that bakes in the case, and then bake these raw materials by the heater of heater and so on.In this bread baking device, owing to need drive the load raw material of kneading with very big motor, the result just makes heat that revolution produces and the frictional heat between belt and above-mentioned two wheels become bigger.Therefore, just need some cooling device and cool off this CD-ROM drive motor.

So far,, proposed all measures, the motor fan be used for cooling off this CD-ROM drive motor specially for example had been installed, or around this CD-ROM drive motor thermal insulation board has been set and passes to motor with the heat of avoiding producing in the process of baking as the cooling way of this class motor.

Unfortunately, in this traditional bread baking device that is provided with the dedicated motor cooling fan, this device must have complicated structure and bigger size, and makes that when this dedicated motor cooling fan is installed number of components and parts increases, and the result has caused very high manufacturing cost.

In addition, because this dedicated motor cooling fan is installed in the place of the wheel that leaves above-mentioned generation heat usually, this just produces the problem that can not fully cool off the heat that goes out because of belt friction loss.As for thermal insulation board is set in roaster, then can produce other problem and promptly only depend on the thermal natural convection of this class thermal insulation board to work, cooling effectiveness is very low.

Consider above problem, the object of the present invention is to provide the bread baking device of the special-purpose cooling fan of the additional particular component of a kind of not conduct, thereby can produce with low cost, at this, be this cooling fan be installed in driving wheel monolithic molding on the drive motor axle as parts, rotate the circulating current that forms by this CD-ROM drive motor simultaneously, the frictional heat that generates in heat of cooling off this CD-ROM drive motor effectively and being produced and the aforementioned belt.

In bread baking device of the present invention, by power transmission component driving force is passed to and to be installed on the plate of kneading that bakes in the case, the invention is characterized in: is an axial end monolithic molding of cooling fan and driving wheel single part, outer cover with some air vents is set simultaneously, and these air vents respectively are located on the base plate under the CD-ROM drive motor and on the upper side wall.

Adopted in the bread baking device of the present invention this, when CD-ROM drive motor begins to rotate, with the driving wheel monolithic molding be that the cooling fan of single part also begins to rotate, so between the bottom of aforementioned outer cover and the air vent on the sidewall, just produced air-flow.Like this, because the frictional heat that produces between the heat that produces in the CD-ROM drive motor and synchronous belt and wheel discharges with said flow, this CD-ROM drive motor and synchronous belt are cooled off effectively.

Because this cooling fan is to form as a wholely with driving wheel, just needn't provide cooling fan as extra parts.

Brief description accompanying drawing of the present invention

Fig. 1 is a side view of having used first embodiment of bread baking device of the present invention.

Fig. 2 is the side view that forms holistic cooling fan and driving wheel.

Fig. 3 is the side view of the second embodiment of the invention basic element of character.

Describe the present invention now in detail.

The contrast accompanying drawing describes embodiments of the invention in detail below.Fig. 1 and Fig. 2 show first embodiment of bright application bread baking device of the present invention, and Fig. 3 shows bright its second embodiment.

The structure of first embodiment is at first described.In Fig. 1, hood 1 is formed shell, and top cover 2 covers this hood 1, and the outer box of baking chamber 3 is installed on the hood 1, in separable mode bread baking case 4 is being installed in the box in addition.Cooperated with a counterpart 6 by the pin 5 that bakes case 4 bottom evaginations, this counterpart 6 engages with keeper 7 on being installed in hood 1 bottom in separable mode.Be provided with one in the bottom of bread baking case 4 and be installed on bread on the axle 8 plate 9 of kneading, assembling one large diameter belt pulley 10 on this bottom of 8 in separable mode.Label 11 stylus pins nail is used for preventing bread raw materials and kneads plate 9 co-rotation that label 22 finger rings are around baking the heater that case 4 is installed.

Be installed on as the driving wheel 14 of power transmission component on the axle 13 of CD-ROM drive motor 12, and this CD-ROM drive motor plays the effect of dynamic force generating unit and be installed on the bottom of hood 1.Synchronous belt 15 hangs between driving wheel 14 and the major diameter belt pulley 10.As shown in Figure 2, cooling fan 16 forms an integral body with driving wheel 14 bottoms.Be formed with some

air vents

18 and 19 on the base plate 17 of hood 1, they are positioned at the bottom of CD-ROM drive motor 12 and major diameter belt pulley 10, also are provided with the venetian blind type air vent that some are positioned at CD-ROM drive motor 12 tops simultaneously on the sidewall of hood 1.Symbol 21 is accused the system device.

The ruuning situation of this bread baking device is described below again.The rotation of CD-ROM drive motor 12 passes to major diameter belt pulley 10 through driving wheel 14, slows down through synchronous belt 15 therebetween, and the plate 9 of kneading then rotates the bread raw materials of kneading by axle 8 in bread baking case 4.Bread raw materials is able to knead effectively in baking case 4 owing to being avoided rotating jointly with the plate 9 of kneading with the collision of the pin 11 that prevents corotation at last.

When cooling fan 16 rotates with driving wheel 14, in hood 1, will generate arrow among Fig. 1 show to air-flow.Like this, when the air from 20 suction of venetian blind type air vent skims over CD-ROM drive motor 12, when the air vent from hood base plate 17 18 is discharged then, the frictional heat that forms in the heat that generates in the CD-ROM drive motor 12 and the synchronous belt is cooled off.

In second embodiment as shown in Figure 3, air-flow flow to air vent 20 from air vent 18 and 19.Because the direction of this air-flow is to be determined by the two relation of the orientation of fan blade and direction of rotation thereof, as long as make a kind of such cooling fan.

As mentioned above, in the present invention, by making cooling fan and driving wheel form an integral body, simultaneously by some air vents are set on hood base plate and sidewall, just can be when starting CD-ROM drive motor, between these air vents, generate air-flow, allow the frictional heat that generates between the heat that generates in this CD-ROM drive motor and speed-governing belt and the wheel discharge, and this motor and belt are cooled off.

In addition, because cooling fan is to form one with driving wheel, the cooling fan of motor needn't be installed as extra parts.Therefore, not only can simplify and install and the minimizing manufacturing expense, can also start cooling fan effectively and drain the heat that generates in the synchronous belt, this is because can cool off near the belt that produces heat.
